145017 Small Heath Coenonympha pamphilus Wingspan 30mm. A tiny grassland butterfly that invariably rests with its wings closed; upperwings are almost never revealed. Underside of forewing is orange with an eyespot; hindwing is marbled grey, brown and buff. Double-brooded: flies May–June and August–September. Larva feeds on grasses and is nocturnal. Widespread but locally common only in southern England; range has contracted because it is restricted to unimproved grassland and does not tolerate modern agricultural practices.
